We're having problems getting the Address Lookup in Maestro to pass the correct format to a TM Service. The same TM Service is being used on a Composer form with no problem. What are the differences between the two if any?

The Mastersoft Harmony package contains both Maestro UI elements and server-side Groovy services that are designed to work with each other. It does not use the same Groovy services as the Composer implementation. This package is currently in use by many clients so I would not expect you to have issues. View the readme file for details around the Short or Long address formats supported by this package.
